Explained simply
Prime Video is Amazon’s subscription streaming service, where films are released alongside cinema titles and made available to watch at home. Horror films range from supernatural stories to thrillers built around real-world dangers, such as animals or isolated locations.
The film centres on a group of friends exploring underwater caves when they encounter a bull shark. Its cast includes Kathryn Newton, Lana Condor, Gavin Casalegno and Nico Hiraga; Jeff Wadlow directed it and also made the 2024 horror film “Imaginary”.
The story sits within a broader run of horror releases across cinemas and streaming services. Films such as “Obsession”, “Hokum” and “Send Help” have helped keep the genre in public view, as studios and platforms continue to release horror for audiences watching in theatres or at home.
